My Outlook for Mac HTML email reply quoted body blank, only headers show
I've been using Legacy Outlook for Mac for years without issues, but since Wednesday afternoon (June 17, CET) something broke after the latest update rolled out. When I reply to any HTML email, the quoted original message is completely blank. Only the From, Date, To and Subject headers show up — the actual email body is gone. It makes it impossible to have a proper email thread because the recipient can't see the conversation history. This started right after Version 16.110 (Build 26061317) was released on June 16, 2026. The release notes only mention "Quality and performance improvements" for Outlook, so whatever changed in this build seems to have broken HTML reply quoting as an unintended side effect. My setup: MacBook Air M5, macOS (Legacy Outlook for Mac Exchange on-premises account (EWS), domain login What I'm experiencing: Replying in HTML mode → quoted body is completely blank, only headers show Switching to plain text → body comes back but with massive blank line gaps throughout (not professional to send) Outlook Web (OWA) → works perfectly fine What I've already tried: Cleared app data (Document Cache + Experimental Features) — no fix Cleared Outlook cache manually — no fix Toggled composing settings — no fix Checked settings in Preferences → Email → Composing — everything looks correct I've also tested Apple Mail as an alternative but it breaks embedded signature images (CID images show as placeholders), and it doesn't support Teams meeting integration — so going back to Legacy Outlook is really the only option for my daily work. Outlook Web App OWA is my current workaround but it's not sustainable long term. I really hope this can be looked at as a regression fix in the next update. Has anyone else experienced this since the June 16 build? Does anyone has this issue as well?Decommission from one tenant to become separate tenant
A customer of mine has been using Office 365 A3 which was actually a tenant for their parent university. Now the child (my customer) wants to become separate entity by having their own Office 365 tenant. How can they move their mailboxes and other data from the parent company? How to route emails to the new tenant (child)? Please guide.
Moving Office 365 Mailboxes to IMAP Servers - What’s the Best Approach
I’ve recently been looking into scenarios where organizations need to move mailboxes from Microsoft 365 to IMAP based email servers, and I noticed this is still a common requirement in many migrations. In most cases, the challenge is not just moving emails, but making sure everything like folder structure, old emails, and user data stays intact without creating too much disruption for users. From what I’ve seen, doing this manually can get very complex, especially when there are multiple mailboxes or large data volumes involved. That’s where migration tools usually come into the picture. Most tools simplify things by handling: 1. Secure connection to Microsoft 365 accounts 2. Bulk mailbox migration 3. Preserving folder hierarchy 4. Reducing downtime during the move 5. Avoiding duplicate data issues One thing I’ve noticed is that running a small pilot migration first always helps. It gives a clear idea of how the actual migration will behave before moving all users. Has anyone here worked on Office 365 to IMAP migration at scale? Would be good to know what approaches or tools worked best in your case and what challenges you faced during the process.
Teams Meeting Add-in Not Appearing in Outlook
The computer was rebuilt from scratch and reinstalled with a clean operating system. After the installation, all required Microsoft applications (Outlook, Teams, etc.) were installed and the user successfully signed in. However, the Teams Meeting add-in is not appearing in Outlook as expected. Within the Outlook Calendar/Appointment window, only the Skype Meeting option is visible, while the Teams Meeting option is completely missing. Checks Performed: New Microsoft Teams is installed and functioning properly. Outlook and Teams are both signed in with the user account. Outlook COM Add-ins have been checked. Disabled Items have been checked. Teams Meeting Add-in for Microsoft Office has been verified. Outlook updates have been checked. Microsoft Teams has been reinstalled. Outlook profile has been verified. Exchange mailbox is active and functioning correctly. Despite all the above checks, the Teams Meeting option is still not displayed in the Outlook Calendar/Appointment window, and only the Skype Meeting integration is available. Expected Behavior: The Teams Meeting button should be available within the Outlook Calendar/Appointment window, allowing users to create Teams meetings and automatically generate Teams meeting invitations. Request: Please why the Teams Meeting Add-in is not being loaded into Outlook and provide assistance in restoring the Teams Meeting functionality within the Outlook Calendar/Appointment interface. Attachments: Screenshot showing the current issue (Teams Meeting button missing) Screenshot showing the expected behavior (Teams Meeting button visible)15 productivity features in the new Outlook for Windows
Hello, Outlook community. I’m Vicki Milton, a Principal Product Manager on the Outlook team. Over the last year, we’ve added important capabilities across areas such as offline support, shared mailboxes, and PST files. Alongside those milestones, we've continued to deliver smaller improvements that help people work more efficiently throughout the day. This article highlights 15 productivity features in the new Outlook for Windows that can help you stay organized, reduce routine effort, and keep important work moving. Mail features Email remains central to how many people manage communications, priorities, and follow-up. Outlook includes familiar tools for composing and organizing messages, along with newer capabilities that can help reduce friction and make inbox management more efficient. Pin a mail: Keep important messages easy to find. The Pin feature keeps a selected email at the top of your inbox so it remains visible as new messages arrive. This can be useful for items you need to reference often or do not want to lose track of, such as travel details, approvals, or active requests. By keeping priority messages in view, Pin can reduce time spent searching and help you stay focused on current work. Snooze a mail: Return messages when they are relevant again. Snooze lets you temporarily remove an email from your inbox and have it reappear at a time you choose. This can help keep your inbox focused on messages you can act on now while ensuring follow-up items come back when they are timely. It is particularly useful for requests that depend on additional information, scheduled tasks, or work you plan to handle during dedicated focus time. Add multiple categories at the same time: Organize messages with fewer steps. If you use categories to manage incoming mail, Outlook makes it possible to apply more than one category in a single action. This can help when you need to capture multiple types of context, such as project, priority, or follow-up status, without reopening menus repeatedly. It is especially useful when processing a large number of messages. Sweep: Reduce repetitive inbox cleanup. Sweep lets you create automatic actions for messages from a specific sender. For example, you can delete promotional mail after a set period, keep only the latest message in a thread, or move recurring updates to a folder. This can help reduce manual cleanup and keep your inbox more focused on items that need attention. Schedule Send: Write on your schedule and deliver at the right time. Schedule Send lets you prepare messages when it is convenient for you and send them later at a time that works better for the recipient. This can improve visibility, support more intentional communication, and reduce the need to rely on reminders or leave messages in Drafts. Simplified folder sharing: Share folders more simply. Sharing a mail folder has traditionally required extra permission steps, especially for nested folders. Now, when you share a folder, Outlook can automatically apply the visibility permissions needed for its parent folders. This can reduce setup effort, help avoid access issues for recipients, and make folder sharing easier to complete with confidence. Calendar and meeting features For many people, the workday is shaped by meetings, schedule changes, and the need to stay aligned on what comes next. Outlook includes calendar and meeting capabilities that can help simplify planning, reduce coordination overhead, and make follow-up easier. Follow a meeting: Stay informed without attending live. The Follow RSVP option lets you indicate that you will not attend a meeting but still want access to the recap. This can be helpful when schedules overlap or when a meeting is useful to monitor without joining in real time. It can help you stay connected to outcomes and shared materials while keeping your calendar more manageable. Save calendar views: Return to the calendar setup you need more quickly. Saved Views let you store specific calendar combinations and switch back to them without rebuilding the same view each time. This can save time for people who move frequently between personal, team, and project schedules. It also can make it easier to review the right set of calendars for different planning tasks. Improved meeting tracking: Work with meeting responses more efficiently. Outlook includes tools that make it easier for organizers to review and manage meeting responses. You can sort attendee lists, search for names in the Tracking view, and copy or download response details when needed. These capabilities can be especially useful for larger meetings where attendance information needs to be reviewed quickly. Meeting recap: Find follow-up materials in one place. After a Teams meeting, the calendar event in Outlook can surface a Meeting recap with links to the recording, transcript, and shared files. This can make it easier to review what was discussed, confirm details, or catch up afterward. By keeping these materials together, Meeting recap can reduce the time it takes to get oriented after a meeting. Filtered views: Reduce visual clutter in your calendar. Filters let you hide meetings you are not attending and limit the distraction of declined or informational events. This can make it easier to scan your schedule, identify conflicts, and focus on the meetings that need your attention. For people with full calendars, it can help make planning more straightforward. Change a recurring event: Update future meetings while preserving earlier ones. When plans change, Outlook lets you edit the current event and all following events in a recurring series. This can make it easier to adjust details such as time, location, or agenda going forward without changing the record of past meetings. It can simplify updates for organizers and reduce disruption for attendees. Personalization and settings Settings can play a practical role in day-to-day productivity. A few adjustments can make it easier to focus, move between accounts and calendars, and work in a way that fits your preferences. Here are several settings-related features that can help make Outlook feel more streamlined and manageable. Rename your email accounts: Make the right inbox easier to recognize. If you use multiple accounts in Outlook, you can assign each one a custom name. This can help you tell accounts apart more quickly, reduce the chance of sending from the wrong inbox, and make navigation simpler as you move between accounts during the day. Modern themes: Choose a look that supports comfort and clarity. Outlook includes theme and color options that let you tailor the experience to your preferences. Visual settings can influence readability and comfort, especially for people who spend much of the day in email and calendar. Options such as Dark Mode and color customization can help make the interface feel easier to use over time. Keyboard shortcuts: Keep familiar ways of working. In Outlook, you can choose the shortcut style you prefer in Settings. This can help you maintain existing habits, reduce adjustment time, and complete common tasks with fewer steps. For people moving from classic Outlook or Outlook on the web, shortcut flexibility can make the transition more consistent. These features reflect a broader effort to help people work more efficiently in the new Outlook for Windows. Whether you are managing a high volume of email, coordinating a full calendar, or tailoring the experience to match your workflow, these updates are designed to reduce effort and improve day-to-day productivity.

Outlook Android “Sync Contacts” disabled for Microsoft 365 Business Standard tenant
I am the Microsoft 365 tenant administrator. Outlook and Authenticator work correctly on Android. The “Sync Contacts” toggle inside Outlook is disabled/greyed out. Native Exchange setup hangs on “Retrieving account information”. No Intune license available (Business Standard tenant). How can I enable Outlook contact synchronization with Android Contacts?Is a COM add-in the only way to add an add-in to a Gmail/IMAP account in classic Outlook?
I have an Outlook web add-in (Office.js, MailApp) that works fine on Exchange Online mailboxes. But on a Gmail account added to classic Outlook for Windows via IMAP, the add-in never activates, as I understand it, web add-ins need an Exchange backend to activate against, which an IMAP account doesn't have. Is that correct? And if so, is a traditional COM add-in (VSTO) the only supported way to surface an add-in on these IMAP/POP mailboxes in classic Outlook, or is there a web-add-in path I'm missing?I built a free, open-source M365 security assessment tool - looking for feedback
I work as an IT consultant, and a good chunk of my time is spent assessing Microsoft 365 environments for small and mid-sized businesses. Every engagement started the same way: connect to five different PowerShell modules, run dozens of commands across Entra ID, Exchange Online, Defender, SharePoint, and Teams, manually compare each setting against CIS benchmarks, then spend hours assembling everything into a report the client could actually read. The tools that automate this either cost thousands per year, require standing up Azure infrastructure just to run, or only cover one service area. I wanted something simpler: one command that connects, assesses, and produces a client-ready deliverable. So I built it. What M365 Assess does https://github.com/Daren9m/M365-Assess is a PowerShell-based security assessment tool that runs against a Microsoft 365 tenant and produces a comprehensive set of reports. Here is what you get from a single run: 57 automated security checks aligned to the CIS Microsoft 365 Foundations Benchmark v6.0.1, covering Entra ID, Exchange Online, Defender for Office 365, SharePoint Online, and Teams 12 compliance frameworks mapped simultaneously -- every finding is cross-referenced against NIST 800-53, NIST CSF 2.0, ISO 27001:2022, SOC 2, HIPAA, PCI DSS v4.0.1, CMMC 2.0, CISA SCuBA, and DISA STIG (plus CIS profiles for E3 L1/L2 and E5 L1/L2) 20+ CSV exports covering users, mailboxes, MFA status, admin roles, conditional access policies, mail flow rules, device compliance, and more A self-contained HTML report with an executive summary, severity badges, sortable tables, and a compliance overview dashboard -- no external dependencies, fully base64-encoded, just open it in any browser or email it directly The entire assessment is read-only. It never modifies tenant settings. Only Get-* cmdlets are used. A few things I'm proud of Real-time progress in the console. As the assessment runs, you see each check complete with live status indicators and timing. No staring at a blank terminal wondering if it hung. The HTML report is a single file. Logos, backgrounds, fonts -- everything is embedded. You can email the report as an attachment and it renders perfectly. It supports dark mode (auto-detects system preference), and all tables are sortable by clicking column headers. Compliance framework mapping. This was the feature that took the most work. The compliance overview shows coverage percentages across all 12 frameworks, with drill-down to individual controls. Each finding links back to its CIS control ID and maps to every applicable framework control. Pass/Fail detail tables. Each security check shows the CIS control reference, what was checked, what the expected value is, what the actual value is, and a clear Pass/Fail/Warning status. Findings include remediation descriptions to help prioritize fixes. Quick start If you want to try it out, it takes about 5 minutes to get running: # Install prerequisites (if you don't have them already) Install-Module Microsoft.Graph, ExchangeOnlineManagement -Scope CurrentUser Clone and run git clone https://github.com/Daren9m/M365-Assess.git cd M365-Assess .\Invoke-M365Assessment.ps1 The interactive wizard walks you through selecting assessment sections, entering your tenant ID, and choosing an authentication method (interactive browser login, certificate-based, or pre-existing connections). Results land in a timestamped folder with all CSVs and the HTML report. Requires PowerShell 7.x and runs on Windows (macOS and Linux are experimental -- I would love help testing those platforms). Cloud support M365 Assess works with: Commercial (global) tenants GCC, GCC High, and DoD environments If you work in government cloud, the tool handles the different endpoint URIs automatically. What is next This is actively maintained and I have a roadmap of improvements: More automated checks -- 140 CIS v6.0.1 controls are tracked in the registry, with 57 automated today. Expanding coverage is the top priority. Remediation commands -- PowerShell snippets and portal steps for each finding, so you can fix issues directly from the report. XLSX compliance matrix -- A spreadsheet export for audit teams who need to work in Excel. Standalone report regeneration -- Re-run the report from existing CSV data without re-assessing the tenant. I would love your feedback I have been building this for my own consulting work, but I think it could be useful to the broader community. If you try it, I would genuinely appreciate hearing: What checks should I prioritize next? Which security controls matter most in your environment? What compliance frameworks are most requested by your clients or auditors? How does the report land with non-technical stakeholders? Is the executive summary useful, or does it need work? macOS/Linux users -- does it run? What breaks? I have tested it on macOS, but not extensively. Bug reports, feature requests, and contributions are all welcome on GitHub.

Exporting Office 365 mailboxes to PST is still a common requirement in many Microsoft 365 environments, especially for backup, compliance, and migration scenarios. While Microsoft offers native options like Purview eDiscovery and Outlook export, many administrators also consider third-party tools when dealing with large mailboxes or bulk export requirements. In real-world scenarios, factors like speed, ease of use, permission handling, and consistency of exported data often influence the choice of tool. Some teams prefer native methods for compliance control, while others explore third-party solutions to simplify large-scale or repeated export tasks. For those working with Microsoft 365, what has your experience been with third-party PST export tools? Have they helped in your environment, or do you still rely mainly on Microsoft’s native options?
